ELECTRICALLY-OPERATED VALVE.

Application led September 27, 1926. Serial No. 138,099. I

of valve construction is shown havin the cast valve body 1, in which is formed the valve seat 2 surroundingr the portl. The valvehead 4 is attached to the valve stem 5, which 1s slidable through the upper lange 6 ot the valve body. The bellows 7 is sealed to the valve head and to the flange 6, and serves to prevent leakage past the valve stem. A hood-Shaped switch housin 8 is secured to-the flange 6, and is provi e'd with oppositely disposed lugs 9. The lugs 9 are the` only portions of which are used for attaching any of the mo v1n,9; parts.' The head- 10 of the bellows 11 is gripped to the lugs 9 by means of blocks ,12, which are drawn up by means ofthe cap screws 13. The plunger 14 is sealed into the lower recessed head 15 of the bellows, and eX- Vtends. slidably through the center of the upper head 10.

The movement is caused by the plunger being operated slightly while the valve is in Contact with its seat, the connection being sufficiently rigid to prevent relative movement when the valve is oi the seat.

Heretofore the vswitch was separately mounted and operably engaged by a' pin or lug Xed to the valve stein. This arrangement did not ermit any movement for operating the swltch afterthe valve was seated,

so'that the switch had to open simultaneously with the closing of the valve. This arrange-l ment also involved complicated constructions and possessed other disadvantages, which it` is desired to overcome in this invention.

This switch 31 may be operated in any desirable manner, as by hand or by means of a thermostatic con- In the open position, shown in Fig. 1, it may be seen that the bellows 11 is collapsed by the -contraction of the Huid enclosed therein, which draws the shoulder 16 of the plunger 14 into Contact with the bellows head 10, which is rigidly secured to the switch housing 8. The spring 27'is extended and Y .holds the plunger pin 22 in contact at the is t ereby expanded. 'Ihe lower head 15 of the bellows then moves downwardly as the fluid continues to expand and drives the valve head 4 into contact with the seat 2,

As soon as the downward motion of the head 4 is stopped, the continued expansion of the bellows moves the end of the plunger 14 downwardly in the sleeve 20. rIhis downward movement of the pin 22 rotates the switch lever 25 so lthat the bulb switch 24 is tilted bulb 24 is tilted to bellows will then f attained -since' all the alinements required are lin relation 4to the sleeve 20.`
